I've got a column of 1700 or so altitudes, ranging from 250 km to 2000km. I would like to go through and filter out those that are closer than a certain range, in this case those that are closer than 5 km. So starting from 250 km, I would skip the next few numbers until I got one that was at least 255 km and keep it. Then I would skip ahead until I found one at least 260 km, and so forth through the whole set.
It's easy (but tedious) to do this manually and I was wondering if anyone know if a filtering function in excel that could help me out. It would not be hard to write a simple C program to do this but its Friday and I don't want to have to do that unless I really have to. ------ Brian
